Application 111ml February This invention relates to improvements inrailway brakesand more particularly to the foundation brake system'andmanually actuated mechanism as installed on :railway` cars. I n otherwords, the invention resides'in `the peculiar combination and relationofthe manually operated brake rigging and `air brake mechanism now ingeneral use. One of the objects of the presentI invention is to provideanlimproved brake system Jfor railway cars of simplefand practicalconstruc' tion and one which may be'manually operated and be as reliableand eficient in use and operation as the ower brake.

A. further object is to`provide a system of the above general characterwhich may .be easily applied to the foundation brake. rigging now in usewithoutmaterial modification.A

i A further object is t0 provide an improved. manually operated brakerigging adapted to have uniform travel regardless of the we ar of thebrake shoes and associated parts.

A further Objectis to provide an improved brake rigging in which themanually oper# ated unit will automatically compensatefor excess travelof the rigging.'

A further object is to provide a quick acting high powered manuallyoperated brake particularly applicable -or use in connection withV thepresent combined air brake and hand brake systems now in general use.

Other objects will be in part obvious and in part hereinafter pointedout in connection with the accompanying sheets of drawings wherein isshown two of various 'possible embodiments of the system and a preferredform of the manually operated mechanism.' In these drawings whereinsimilar parts are denoted by corresponding reference characters- Figure1 isa diagrammatic view showing suiiicientparts of the completesystemVas to en able one to thoroughly understand the same.

Figure 2 is a similar view showing armodified system;

. Figure 3 is a detail partial sectional view of the brake operatingmechanism; and` Figures 4 and 5 are detail views of certain parts.

shown theV generalhand brake arran ement 10, preferably. attached to oneend o av car of any desired type. This mechanism is pro- `vided with 'anactuating chain 11 passing around 'a sheave 12 thence back to the -deadlever 13 of the foundation brake""rigging.

,This lever 13 is connected through tie rod 14 `to cylinder lever 15which is, in turn, con- 'nected to the piston rod 16 actuated fromv theair c'ylinder17. The leversv 13 and 15 are connected through to rods,`18 withthe brake riggingon the truc at the opposite ends of the car.This Vgeneral mechanism is all of well. knownarrangement andneedsnofurther detailed'descriptiomi It will be noted, however, that inonefrespect V the arrangement is thereverse ofthe usual'comf` bination.In other wrdsasherein shown, the handbrake `actuating'm'echanisn'r isattached to one end ofthe dead or-'loating cylinder lever 13, the end ofwhich lever is adapted to travel in the' slotted guide 20 'secured tothe'rear of the airbrake cylinder. Inasmuch as the lower end VAof thelever 13 is .prevented from moving relatively towards the left as.

shown in Figure 1, due to the holdingl mechanism associated with-thehandbrake and later more fully described; This lower end of the lever 13may be considered ixed when air power is applied. On the other hand,

when the handbrake is applied, then the live and dead levers will moveto substantially the position sho'w'n in the dotted lines. The'handactuating mechanism is of-that type which will permit only apredetermined amount of chain to be unwound therefrom and since it isconnected directly to the cylinder floating lever by the chainconnection 11 a seveninch return pistontravel means the unwind.

inches since the proportioning of the levers is the same. By the termchain as herein used and in the claims, itis, of course, to be interreted broadly as denoting a flexible v mem er as wellasto include theconnecting links, as shown, which with'some types oi cars are moredesirable.

In Figure 2 the hand brake arrangement is substantially the same. exceptthat the cylinder 20 is reversed and works in harmony with thehand'brake. In this case the slotted piston rod 21 is provided at itsend with a slot 22 seven or eight inches inlength to correspond with thenormal piston travel. This push rod is fastened'to a hollow piston bymeans of a 'clutch 19 freely operating in one way and locked againstmovement in the opposite-direction, such, for example, as the use of aratchet or dog construction. `Whenv the handbrake is applied by theoperator,v

should the cylinder lever 23 which carries a pin cooperating with theslot '22 in the telescoping rod 21 exceed in movement the length of thisslot 22, then the telescoping part 21 of the piston will be forciblypulled out thru the holding mechanism 19 relatively towardsv the rightto the same extent as Vthe excess travel of the cylinder lever 23 overand above the length of the slot 22. Also the automatic stop in thehandbrake mechanism shown in Figure 4will on release prevent the drum 31from unwinding more than a predetermined amount of chain equal to thelength of the slot` 22 thereby insuring or establishing proper brakeshoe clearance and desiredpiston travel at the next application of thepowery brakes.

When the brake shoes need renewal, as in Figure l, it is only necessaryto drop the automatic holding pawl in the hand brake, thus permittingallfotthe chain to unwind and allow the parts to go to full releaseposi' tion. With the form shown in Figure 2, the holding clutch dog 19is released and the telescoping part 21 of the piston forced inwardly tofull released position. flhe new shoes are applied to the brake riggingand preliminary adjustment `of `the truck brake levers made ifnecessary." ;'Then,. on the iirst application of the hand brake, allofthe excess travel of the entire foundation brake rigging is taken up,and simultaneously the telescoping piston rod is adjusted to properrelative position with respect to the piston in the cylinder -so that onthe first application ot the power brakes, the air piston will move thedesired'seven inches. Of course, it is to be understood that in usingthe .arbitrary distance of seven inches, ,this indicates the normal,standard piston travel of thecar at rest.

When thecarisrin motion, there is, due to' looseness inthe king-pins,journal boxes, etc.,

a slightly greater distance to be traversed before ythe brakes' areeffectively applied,

being perhaps a total of eight inches or eight and a half inches.4v

This preliminary explanation of Figures 1 and 2 isvfor the purposeofshowing the relationship between the hand brake mechanism and thecylinder lever system in order that Ithe unique and novel relationshipof these parts, due to their .peculiar construction and arrangement,will be more apparent. The cylinder lever system diagrammaticallyillustrated in- Figure 2 is an old, well known and conventional typewith the exception of the hangers supporting and limiting the re'- turnmovement of the cylinder levers themselves, the purpose of which behereinafter more fully pointed out. Referring now to Figure 3 of the.drawings, there is shown a casingV 30 provided with-a drum 31 .uponwhich -the chain 11 is adapted to be wound. A main actuating or handWheel 33, drives shaft 34, provided with beveled gear 35, which, inturn, meshes withv `engagement with the ratchet by means of a pivotallymounted weight 44. This collar 41 may be turned or reversed and lockedin any desired position by means of the lug 42- adapted to engage arecess in the collar 40.

Outside of the large bevel gear 36 is aspocial holding ratchet 45 whichis attached to and moves with the gear at thesame speed. The teeth ofthis ratchet are covered throughout the greater portion thereof by meansof l a thin springsteel protection covering 46,

as shown more completelyin Figure 4, which hugs the periphery of theteeth with sufficient friction to prevent ordinary relative movement yetslips relatively thereto when occasion demands as wear of the partstakes place. It will be noted that this covering or shield is providedwith an ear 47, as shown in full lines in Figure 4, when the parts are.in full released position, but moves to thev dotted line position at 48when the brake is applied.- Should vthe ratchet continue to revolve in acounter-clockwise direction after the'earreachesthe position 48` itstrikes against the hub 50 of gravity actuated pawl 51 and is caused toslip relativelyto the ratchetwheel 45 to an extent equal to that of theexcess travel. The chainsheave 31 will, under these. circumstances,take. up more than' the usual seven inches' of slack chain, and onrelease'of the brakes the pawl 51 is raised and will ride on the upperor outer surface of the shield unless it reaches the gap lll) n 55 Ainthe uncovered portion whereu on it i follows.

"Figure 5 is to Figure 4, hut a power pawl is manna y moved outmultiplying device, such Yas gears 52-53, is

employed, the gear 52 heing on the brake staff.

While itis believed that the operation oi thisxdevice is perfectly clear-rom the above description, a brief 'statement thereo'is as Referring@Figures 1,3 ma aa be noted that when the handwheelfl is rotated, thebrake is applied and pressure maintained byreason of the pawl andratchet' mechanism rection until the hole comes opposite 'the pawl 51whereupon Vtheipawl drops-into "engagement with the teeth ofratchet'45'and prevents a Vfurther of the chain 32 fromthe drum 31,thereby positively 1nsuring a uniform brake actuating movement of thehand brake rigging. When the brakes are next applied, it will .only henecessary to give the drum approximately two-thirds of a turn in orderto-obtajn full braking pressure. Y Y

It, due to wear-tof the parts, this two-thirds of a turn is insuicientto taire up 'alici the Y excess travel, thesleeve 46 automaticallyadjust itself by-reason of the engagement oi the stop 48 withpinvl) toanew position upon the ratchet, and Yin this manner, the

brake rigging isV automatically adjusted at all times. i.

Referring back to Figur-cl2, in order that the c0operation-between--thehand and power brakes may beA more apparent, attention is directed tothefact that opposed to the `cylinder lever 23 is the dead or oatmgcylinder lever connected therewith by means ci tie rods 6l. These levershave their opposite ends connected to pull rods 62 extending in oppositedirections. and connected with the upper ends of the live truck levers63. The lower ends of these levers are connected to the dead trucklevers 64 by means oi bottom tie rods 65. The upper ends oi the deadlevers are supported in adjustable hangers 66 which in the present case,as herein shown,

are mounted on truck holsters 67. 0i course,

the truck levers. carry ,bralre heams having shoes 68 adapted. to coactwith the the pe her ofthe chain ripheries of. the-adjacent truck wheels.All

of Vthis mechanism, immediately above described, is of. substantiallystandard construction dii'ering slightly in different types of cars, butheretofonei'io one has apparently appreciated the importance ofutilizing and accurately positioning the cylinder` lever hangers 70 withrelation to the truck brake rigging and piston travel. These hangers 70,which may bevo theusual inverted, U-shaped bars depending from the underside of the car body or slots in the draft sills when an all metall caris equipped, are

adapted to limit the adjusting movement of the truck brake levers andpermit independent. adjustment of each truck'brake rigging"V withoutvdisturbing the relative angularity of either the cylinder or the truckbralrelever's at theoppositeiend of the car. For instance,

as herein shown, when new brake shoesare applied to the brake beams ofone truck and the levers adjusted tosubstantially desired position, themechanic in charge merely removes the pin 71 'and pulls the upper endof'V the dead truck leverl 64towards the yadjacent -end of the car asfar as it will go. This brings the brake shoes into contact with theperipheries of the wheels or. into appliedpo` sition. Then by droppingback one hole on regulator 66, the brakes automatically release fromengagement with the wheels. and substantially the desired brake shoeclearance is obtained. This major adjusting.moveinent,

however, does not affect the remainder of the foundation gear, for thecylinder levers are snug vagainst the end of their hangers 70, and thepulling movement exerted upon the' upper ends of the dead levers 64isstopepd ico at that point of engagement between the cyl- -inderleverand 'its supporting hanger.

In thismanner not only is thel independent adjustment of eachtruckbrakeriggmg permitted Without seriouslyA changing the angularity ofany of the levers, .but the piston travel (neither too short 'nor toolong) and the hand 'brake travel is maintained more nearly constant.`.The 'subsequent ineradjustment for both of' these mechanismspermittedby their associated parts may be then more easily and quicklyestablished on first application `of V the brakesv and maintainedthereafter.

From the above, itwill be apparent that if the normal hand brake travelof seven inches provided for by the' slot 22 be exceeded, such movementwill automatically adjust the izo piston travel by pulling out thetelescoping part 21 of the piston lpast the holding means 19.

It will thus be seen that the hand brakeV mechanism. above described isparticularly applicable for use with the foundation bralre rigging ofcars of that type adaptedto have semiautomati'c adjustment to compensatefor wear of the parts, and the bralre mechanism the foundation brakerigging, hand brakev mechanism, means directly incorporated thereinadaptedto establish uniform piston travel when the air brakes areactuated, and
